Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0027] In the prior art, the semi-finished powder has a small particle size and poor fluidity, which affects the stability of the spiral conveyor sheet. In severe cases, the spiral conveyor sheet may be blocked, resulting in poor conveying effect of the spiral conveyor when conveying the semi-finished powder.

[0028] Based on the above reasons, the embodiment of the present application provides a spiral conveying device for conveying powder coatings, including a tube body, a motor and a spiral conveying sheet, wherein the motor is fixedly connected to the end of the tube body, the spiral conveying sheet is made of metal, the spiral conveying sheet is in a compressed state and the two ends of the spiral conveying sheet are rotatably connected to the tube body, and the motor and the spiral conveying sheet are transmission-connected. The spiral conveying sheet in the embodiment of the present application conveys materials in a compressed state, so that the spiral conveying sheet has a certain toughness and deformation degree, and can leave a certain deformation margin when the fluidity of the coating powder is poor, thereby improving the stability of the spiral conveyor when conveying coating powder, avoiding the blockage of the spiral conveyor, and improving the use effect of the spiral conveyor.

[0029] In some scenarios, a spiral conveying device for powder coating conveying according to an embodiment of the present application can be used in the conveying of finished and semi-finished coating powders. It is suitable for conveying coating powders with a particle size of 10-100um and can avoid clogging of coating powders.

[0030] The following is a detailed description of a screw conveying device for conveying powder coatings provided in an embodiment of the present application with reference to specific examples.

[0031] Figure 1 A schematic cross-sectional structure diagram of a spiral conveying device for conveying powder coatings provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the spiral conveying device for conveying powder coating comprises a tube body 1, a motor 2 and a spiral conveying sheet 3, wherein the motor 2 is fixedly connected to the end of the tube body 1, the spiral conveying sheet 3 is made of metal, the spiral conveying sheet 3 is in a compressed state and both ends of the spiral conveying sheet 3 are rotatably connected to the tube body 1, and the motor 2 and the spiral conveying sheet 3 are transmission connected.

[0032] like Figure 1 As shown, the tube body 1 is used to contain the coating powder, and the motor 2 and the spiral conveying piece 3 are used to convey the coating powder in the tube body 1 .

[0033] Structurally, the motor 2 is fixedly connected to the end of the tube body 1 , and the motor 2 is transmission-connected to the spiral conveying piece 3 .

[0034] After assembly is completed, the spiral conveying sheet 3 is made of metal, the spiral conveying sheet 3 is in a compressed state and the two ends of the spiral conveying sheet 3 are rotatably connected to the tube body 1, so that the spiral conveying sheet 3 has a certain compression elasticity. When the fluidity of the paint powder is poor, the spiral conveying sheet 3 can leave a certain deformation margin, which improves the stability of the screw conveyor when conveying paint powder, can avoid blockage of the screw conveyor, and improves the use effect of the screw conveyor.

[0035] The beneficial effect brought about by the above implementation method is that it can avoid the blockage of the screw conveyor and improve the use effect of the screw conveyor.

[0036] In some implementations, both ends of the spiral conveying sheet 3 are rotatably connected to the tube body 1 via thrust bearings.

[0037] In terms of structure, both ends of the spiral conveying piece 3 can be rotatably connected to the tube body 1 through thrust bearings, thereby reducing the friction force of the spiral conveying piece 3 when the spiral conveying piece 3 rotates in a compressed state.

[0038] The beneficial effect brought about by the above implementation method is that the friction force of the spiral conveying piece when the spiral conveying piece rotates in a compressed state is reduced, so that the coating powder is easily conveyed.

[0039] In some implementations, the first end of the tube body 1 is provided with a first baffle 11, a first thrust bearing 12 and a first rotating plate 13, the two ends of the first thrust bearing 12 are respectively abutted between the first baffle 11 and the first rotating plate 13, the first baffle 11 is used to limit the first thrust bearing 12, the spiral conveying plate 3 is fixedly connected to the first rotating plate 13, and the output shaft of the motor 2 is fixedly connected to the first rotating plate 13.

[0040] Figure 2 A schematic diagram of the partial structure of a feeding port of a spiral conveying device for conveying powder coatings provided in an embodiment of the present application is shown in FIG. Figure 2 As shown, the first end of the tube body 1 is provided with a first baffle 11, a first thrust bearing 12 and a first rotating plate 13, and the two ends of the first thrust bearing 12 are respectively abutted between the first baffle 11 and the first rotating plate 13, so that the first baffle 11 can limit the first thrust bearing 12, and the first rotating plate 13 can rotate relative to the first baffle 11.

[0041] Exemplarily, the first baffle plate 11 may be connected to the first end of the tube body 1 by bolts, or the first baffle plate 11 may be connected to the first end of the tube body 1 by welding.

[0042] Structurally, the spiral conveying piece 3 is fixedly connected to the first rotating plate 13, and the output shaft of the motor 2 is fixedly connected to the first rotating plate 13, so that when the motor 2 rotates, it can drive the first rotating plate 13 to rotate, and then drive the spiral conveying piece 3 on the first rotating plate 13 to rotate to transport the coating powder.

[0043] Structurally, a roller bearing may be provided between the first baffle plate 11 and the tube body 1 . The roller bearing is sleeve-connected in the circumferential direction of the first baffle plate 11 , so that the roller bearing can limit the first baffle plate 11 in the circumferential direction of the first baffle plate 11 .

[0044] The beneficial effect brought about by the above implementation method is that the first baffle limits the first thrust bearing, thereby limiting the spiral conveying piece, and the friction force of the spiral conveying piece during rotation is reduced by the first thrust bearing.

[0045] The beneficial effect brought about by the above implementation is that the roller bearing between the first baffle plate and the tube body can provide support between the first baffle plate and the tube body, thereby improving the stability of the spiral conveying sheet when rotating in the tube body.

[0046] In some implementations, a first sealing ring 14 is provided between the first rotating plate 13 and the tube body 1 .

[0047] like Figure 1 As shown, a first sealing ring 14 is provided between the first rotating plate 13 and the tube body 1 , and the first sealing ring 14 can seal between the first rotating plate 13 and the tube body 1 , thereby preventing coating powder from leaking between the first rotating plate 13 and the tube body 1 .

[0048] Structurally, when a roller bearing is provided between the first baffle 11 and the tube body 1 , the first sealing ring 14 is provided on a side away from the motor 2 , so as to seal the paint powder in the tube body 1 .

[0049] The beneficial effect brought about by the above implementation manner is that the first sealing ring prevents the coating powder from leaking between the first rotating plate and the tube body.

[0050] In some implementations, a feed port 101 is provided on the tube body 1 near the motor 2 .

[0051] like Figure 1 As shown, a feed port 101 is provided on the tube body 1 near the motor 2, so that the coating powder can be fed through the feed port 101 near the motor 2. In the process of conveying the coating powder, when the spiral conveying piece 3 is deformed, the feeding can be done at one end of the spiral conveying piece 3 near the feed port 101, thereby avoiding a greater deformation of the spiral conveying piece 3.

[0052] The beneficial effect brought about by the above implementation method is that when the spiral conveying piece is deformed, the material can be fed at the end of the spiral conveying piece close to the feed inlet, thereby avoiding a greater deformation of the spiral conveying piece.

[0053] In some implementations, the second end of the tube body 1 is provided with a second baffle 15, a second thrust bearing 16 and a second rotating plate 17, and the two ends of the second thrust bearing 16 are respectively abutted between the second baffle 15 and the second rotating plate 17. The second baffle 15 is used to limit the second thrust bearing 16, and the spiral conveying plate 3 is fixedly connected to the second rotating plate 17.

[0054] Figure 3 A schematic diagram of the partial structure of a discharge port of a spiral conveying device for conveying powder coatings provided in an embodiment of the present application is shown in FIG. Figure 3 As shown, the second end of the tube body 1 is provided with a second baffle 15 , a second thrust bearing 16 and a second rotating plate 17 , and both ends of the second thrust bearing 16 are respectively abutted between the second baffle 15 and the second rotating plate 17 , so that the second rotating plate 17 can rotate relative to the second baffle 15 .

[0055] Structurally, the second baffle plate 15 is used to limit the second thrust bearing 16 , and the second baffle plate 15 is fixedly connected to the tube body 1 .

[0056] Structurally, the spiral conveying piece 3 is fixedly connected to the second rotating plate 17 , so that the spiral conveying piece 3 can rotate along with the second rotating plate 17 .

[0057] Likewise, a roller bearing may be provided between the second rotating plate 17 and the tubular body 1 , so that the second rotating plate 17 can be circumferentially oriented in the tubular body 1 , thereby improving the stability of the second rotating plate 17 when moving in the tubular body 1 .

[0058] The beneficial effect brought about by the above implementation is that the spiral conveying sheet can rotate with the second rotating plate, and the second thrust bearing can reduce the friction force between the second baffle plate and the second rotating plate during relative rotation.

[0059] The beneficial effect brought about by the above implementation is that the second rotating plate can be circumferentially oriented in the tube body by the roller bearing, thereby ensuring the stability of the second rotating plate when moving in the tube body.

[0060] In some implementations, a second sealing ring 18 is provided between the second rotating plate 17 and the tube body 1 .

[0061] like Figure 3 As shown, a second sealing ring 18 is provided between the second rotating plate 17 and the tube body 1 , and the second sealing ring 18 can seal between the second rotating plate 17 and the tube body 1 , thereby sealing the coating powder from leaking.

[0062] The beneficial effect brought about by the above implementation manner is that the second sealing ring can seal between the second rotating plate and the tube body, thereby sealing the leakage of paint powder.

[0063] In some implementations, a discharge port 102 is provided on the tube body 1 near the second rotating plate 17 .

[0064] like Figure 3 As shown, a discharge port 102 is provided on the tube body 1 near the second rotating plate 17 , and the discharge port 102 can be used for unloading at the end away from the motor 2 .

[0065] The beneficial effect brought about by the above-mentioned implementation method is that when the spiral conveyor plate is deformed due to the interaction with the coating powder, the deformation degree of the end of the spiral conveyor plate away from the motor is greater, and the discharge port can unload at the end away from the motor, thereby improving the stability of the end of the spiral conveyor plate away from the motor.

[0066] In some implementations, a side of the cross section of the spiral conveying piece 3 close to the discharge port 102 is provided with an inclined surface 31 , and the inclined surface 31 is inclined from the inner wall of the tube body 1 toward the center of the tube body 1 along a direction away from the discharge port 102 .

[0067] Figure 4 A schematic diagram of the cross-sectional structure of a spiral conveyor sheet provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, an inclined surface 31 is provided on the side close to the discharge port 102 on the cross section of the spiral conveying piece 3. When the coating powder is conveyed, the inclined surface 31 is a working surface that directly acts on the coating powder. The inclined surface 31 is inclined from the inner wall of the tube body 1 toward the center of the tube body 1 along a direction away from the discharge port 102, so that the coating powder can move from the side close to the inner wall of the tube body 1 toward the side of the center of the tube body 1, thereby reducing the friction between the coating powder and the inner wall of the tube body 1, and avoiding the coating powder from blocking the tube body 1 during the conveying process.

[0068] The beneficial effect brought about by the above implementation is that the coating powder can move from the side close to the inner side wall of the tube body toward the side of the center of the tube body, which can avoid the blockage of the conveying device.

[0069] In some implementations, the inclination angle of the inclined surface 31 is 3 degrees to 10 degrees.

[0070] For example, Figure 2 As shown, the inclination angle of the inclined surface 31 may be 8 degrees.

[0071] The beneficial effect brought about by the above-mentioned implementation method is that the inclination angle of the inclined surface is 3 degrees to 10 degrees, so that the coating powder can move from the side close to the inner wall of the tube body toward the side of the center of the tube body, while ensuring the force acting on the coating powder along the circumferential direction of the tube body, thereby ensuring the conveying effect of the conveying device.

[0072] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
